I had hackers experienc in Battle Royale servers, so i don't know if that's BR team's fault, but essentially there were people spawning rochet launchers at the biginning. Also in Ghost Hotel you are suppose to find only pistols but there were people with 50 cals and shit.
If i talk in direct chat in a server with more than 20 people the only things they'll hear is "He..y...Su..p".
The bigger problem still game random crashes, where the game basicaly stop wortking after joining a multiplayer game, and fps going crazily low in populated servers.
There are fps problems with the render in single player as well, i can get 60 fps in a field and 8 up to 26 in town, that's simply ridicolous, sorry.
Oh and a 20 cm tall fence can still blow up a offroad going 40Km/h.
You can blame on server efficiency but those servers are in your game.
